INTERLOCKINGFIRE BRICK FOR ARCHES.

Application filed May 9,

T all whom it may concemij Be it known that I, WALTER J. a citizen oftheUnited States, residing at Binghamton, in the county of Broome and State of New York, have invented certain new and useful Improvements in Interlocking Fire Bricks for Arches, of which the following is a specification. Y My invention relates to an lmprovement in interlocking fire brick, in WhlCll means are afforded for securely. locking and fas tening the brick in the wall or arch where used and made to present a greater resistance to the heat and to disintegration, and

it has for its object to provide means for easilybut securely formingo'an interlocking union of the blocks when placed in an arch or wall and to afford greater resistance against heat, and the deteriorating effects of constant use.

With these objects in view, my invention consists in certain novel features of conlaylng the narrow face: of the blocks towards struction and arrangement of-parts as will be hereinafter fully described and pointed. out in the claims,'reference being had to the accompanying drawings, in which:

Fig. 1 is a side elevation of my devlce, showing the recess in the side thereof,

Fig. 2 .is an end view of my device. I Fig. 3 is a perspective view of a part of mydevice.

Fig. 4 is a front view of a fragmentary part of arch con'structed with my device. Fig. 5 is a front view of fragmentary part of an arch constructed with my device. Fig. 6'is afront view of a fragmentary part of an arch constructed with my device. Fig. 7 is a perspective view showing the 40 interlocking features of my device.

I parts in each of the several figures of the drawings. I

In carrying out my invention, I provide a fire brick; A. of rectangular formation shown, having the outer top and bottom surfaces or faces I) and 0; the face I) being.

somewhat wider than the face a. rendering the block Ain slightly wedged shaped formation- In the opposite sides of the body A, I have inlet the horizontal rectangular recess 03; as afurther part of my device, I

formedof firebrick material, and adapted to fit in and rest in the. recesses d, d, and the key 6 may be securely mounted therein, by the application in any convenient manner of a coating or filling of cement, or other like material. In the application of the key to the bricks, and the recesses "thereof, the keys e, care so applied to the blocks A, A as to break joints in the center of the blocks A, A, as shown in Fig. 7 and thus forming a continuous surface across the end joints .of the blocks A, A when laid, as shown in Fig. 7 In the application of my device to the formation of the side walls of a furnace archor structural may have the elongated rectangular key 6, also lay the blocks of 7 .the side walls with the alternate wide and:

narrow surfaces of the blocks towards the the interior face of. the arch, as shown in Figs. 4. 5 and 6, withthe locking keys 0, e

insertedv in the recesses,=d, d bet-ween each 'block'as before described. For example in Figs. 5 and 6'. the wall is laid with block faces, alternating, b, c, b a, presenting the" alternate wide and narrow surface of the In the foras shown in Figure 6 and elect to use the same, or other material of like formation to give the right angle formationto the arch. In operation 'while the'heat and flame may slowly disintegrate the cement'between the blocks on the interior of'the wall surface,

its progress and effects find an effective re sistance. in the surface of the key 6, when reached and further progress up or down the surface of the key, is effectively resisted by the angle of therecess supporting the. key. Thus the arch wall and side walls so constructed will not fall or sag but offer a firm resistance. to lateral or downward vertical pressure,

Having thus v I' clai-m as new and for which I desire Letters Patent, is as follows:

An arch for furnaces and thelike, having described my invention what vertical side Walls and arcuate top Wall, said the recesses in, the bricks the said keys arch being formed of Wedge shaped bricks breaking joint intermediate the ends of the having locking recesses in each opposite side brick, and means for securing the keys in 10 face, the vertical Walls of the arch being place;

5 formed by arranging each alternate brick of In testimony whereof I have affixed my .a row with .itsnarrovv racetoward the intesignature. l

I rior of'the arch, locking keys for engaging WALTER J. WILLIAMS.
